Room regressed into partial state

### Description

A private, encrypted room I am in on my server recently got upgraded to v12, however I can no longer use it as it is in a partial state... state. I joined the room on the affected server thirteen events after the `m.room.create` event was spawned, and was able to use the room just fine between 2026-01-27 and 2026-02-09. However, today, I noticed my clients could not encrypt messages, and consequently couldn't send anything. My other server worked fine, so I took a look at my logs, and saw this:
```
master-all.log:2026-02-10 02:51:27,660 INFO synapse.storage.util.partial_state_events_tracker (GET-319266): Awaiting un-partial-stating of room !ef2bukT8lUpCA5NxkhMkqGEsn58bCBxI-74il9Gq8Rg
```

I do not know why this has happened - the room was not previously "partial", and then something changed, and now it *is* partial. It is also not un-partialing itself, just claiming it's waiting for it. Restarting the server did not fix this issue.

### Steps to reproduce

No concrete repro, I'm not even sure what has caused this. The only thing I can see that might be related is I updated my global profile at 20:28 on 2026-02-09, which was fine, but seems to have been the last time I was able to use the room properly. Maybe updating the membership event somehow caused Synapse to assume the room was partial? History is set to `invited`, however I was not invited, I joined via a restricted join rule.
